I have code like the following to test for existence of a file. I know the
file is there, but File.Exists returns FALSE. The problem appears to be
that the file is in a directory beneath "My Documents". When I move it to a
directory directly under the root, File.Exists returns TRUE. So I tried
using FileIOPermission to give me rights to read it, but still no luck. Any
suggestions? Thanks...

I'm using File.Exists to test a file on my C: drive.
My program was strongly named and had caspol -af run on it to allow it to
run from the network.
There are 3 ways I am doing this:
1) Run from my C: drive, File.Exists works properly and says
C:\Temp\test.txt exists
2) Run from my H:\ (network) drive, File.Exists says the file doesn't exist.
3) Run from Visual Studio debugger, with project configuration property

I am using the System.IO.File class to determine if a file exists on a
network share.
The File.Exists method keeps returning false, even though the file does
exist. The MSDN documentation states,
"If the caller does not have sufficient permissions to read the specified
file, no exception is thrown and the method returns false regardless of the
existence of path."

This is a tough one, but here goes.
I have a webform textbox where users input a filepath. For example:
\\servername\sharename\file.xls. Is there anyway that I could use VB code to
verify that the filepath and filename are valid after the user has input
them? Basically this would serve to quality check whether or not the user
has input the correct file path.
Thanks.

I am trying to see if a file exists in a virtual directory, and if so run a
method. I try doing File.Exists and the method runs but the file isn't there.
Is there a web version of File.Exists or some otherway to get this type of
functionality without too much heartache???
Thanks

Hi there. I am parsing a text file and as I parse each line I need
to go out to two different directories and check to see if any files
beginning with the string I just parsed exist. For example... if the
first line in my text file is AS1501 then I need to check Dir1 and see
if there are any files that begin with AS1501 then I need to go to
Dir2 and check there also. I am trying to check using the following
code...

How do I do a client-side check to see that a file exists before
attempting to upload it? I am trying to avoid the "Access denied"
error I get on form submission if an invalid name is entered in the
textbox.
This page does it beautifully:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...
